gsxdsm 7911fdb9b1 fix(release): preserve distilled changelog summaries across releases
syncRootChangelog rewrote every prior release from raw package notes, so only
the latest distilled Highlights view survived. Re-emit already-distilled bodies
on sync, keep the archive pointer outside version sections, and restore wiped
summaries from release history.
